Phosphate Assessment in Chronic Kidney Disease Patients Study (PACK)

The proposed pilot feeding study aims to explore novel pathways in phosphate metabolism and identify new biomarkers, as well as to develop a compound index for assessing phosphate overload with high validity and reliability. Investigators will address the following specific aims: 1). To explore novel pathways of phosphate metabolism and assess the influence of CKD status on these metabolic pathways. 2). To identify novel biomarkers for phosphate overload that reflect changes in dietary phosphorus intake. 3). To develop a compound phosphate overload index that measures dietary phosphorus intake with high validity and reliability. This study will provide novel insights into phosphate metabolism and the assessment of phosphate overload in CKD patients. This investigation aims to provide preliminary data to further studies for the development of reliable biomarkers in CKD patients, which could contribute significantly to early interventions and improve health outcomes.

Leg Heating in Pregnant Women With Obesity

Obesity is a major risk factor for hypertensive disorders of pregnancy (HDP). The underlying mechanisms are largely unclear, but maternal vascular endothelial dysfunction is likely involved. Endothelial dysfunction in HDP could be attributed to 1) alterations in the L-arginine/nitric oxide (NO) pathway, and 2) an increase in endothelin-1 (ET-1). Additionally, augmented sympathetic vasoconstriction may also contribute to HDP. Chronic (repeated) whole-body heat exposure has been shown to increase NO bioavailability, decrease ET-1, and cause functional and structural adaptations in the vasculature. All these can improve vascular function, attenuate sympathetic (re)activity, lower blood pressure (BP), and reduce cardiovascular risk in non-pregnant individuals. Whether this is also true after regional (leg) heating in high-risk pregnant women is unknown. The investigators' central hypothesis is that chronic leg heating will be effective in improving vascular endothelial function and attenuating sympathetic vasoconstriction, leading to a reduction of the risk for HDP in pregnant women with obesity. The overarching goal of this proposal is to determine the vascular and neural effects of chronic leg heating in obese pregnancy. The study team plans to enroll pregnant women with obesity between 12-14 weeks of gestation and randomly assign them to either an intervention group or a control group (1:1 ratio). Participants in the intervention group will perform 16 weeks of home-based leg heating using a portable sauna blanket up to the hip (temperature of the blanket will be set at 65°C, 4 times/week, 45 min/session), whereas women in the control group will set the temperature of the blanket at 35°C at the same frequency and duration. Participants will be evaluated at baseline and then at 28-30 weeks of gestation. Aim 1 will determine the effects of chronic leg heating on maternal vascular function and surrogate markers of HDP. Aim 2 will determine the effects of chronic leg heating on sympathetic vasoconstriction and BP. Findings from this project will provide insight on the extent and potential mechanisms of how chronic leg heating works for improving vascular endothelial function and sympathetic vasoconstriction in pregnant women with obesity. Results obtained will set a foundation for future large multicenter clinical trials to determine the efficacy and generalizability of home-based leg heat therapy as a safe, ease-of-use, cost-effective, and non-drug approach for reducing the risk of HDP.

The Modulatory Effect of Female Sex Hormones on Spinal Neuroplasticity (TMSpine)

The goal of this project is to test our central hypothesis that the spinal cord neuroplasticity in females will be modulated by the level of estradiol concentration. under aim 1 we will determine the influence of estradiol fluctuations on spinal circuit excitability post afferent (sensory) mediated subthreshold motor priming in young healthy females and males. We will use an established repetitive peripheral nerve electrical stimulation with a stimulation intensity below the motor threshold to prime the spinal motor circuits. under aim 2 we seek to characterize the input output property of spinal circuit excitability after descending drive (motor) mediated priming in young healthy male participants. in aim 3 we will examine the influence of estradiol fluctuations on descending drive mediated motor priming in young healthy females.

EffCaMgCit to Prevent Mineral Metabolism and Renal Complications of Chronic PPI Therapy

Proton pump inhibitors (PPIs) are widely used for the control of gastric ulcer-gastritis, erosive esophagitis (gastroesophageal reflux disease), peptic ulcer disease (duodenal ulcer), and heartburn. Despite their efficacy, their use has been implicated in possibly causing fragility fractures (osteoporosis), hypomagnesemia (magnesium deficiency) and increased risk of chronic kidney disease (CKD). The current trial represents the investigators ongoing effort to discern whether these complications could be averted by effervescent calcium magnesium citrate (EffCaMgCit).

Emotional Cognition: Establishing Constructs and Neural-Behavioral Mechanisms in Older Adults With Depression (ENSURE)

This is a cross-sectional pilot study designed to establish hot and cold cognitive functions and underlying neurocircuitry in older adults with MDD. The investigators will study 120 participants aged 21-80 years old with MDD. All participants will undergo clinical and neurocognitive assessment, and Magnetoencephalography (MEG)/Magnetic resonance imaging (MRI) procedures at one time point. The investigators will also enroll 120 demographically matched comparable, never-depressed healthy participants (controls) to establish cognitive benchmarks. Healthy controls will complete clinical and neurocognitive measures at one time point. To attain a balanced sample of adults across the lifespan, the investigators will enroll participants such that each age epoch (e.g., 21-30, 31-40, etc.) has a total of ten subjects (n=10) in both the healthy control cohort and depressed cohort.

The Role of Sirolimus in Preventing Functional Decline in Older Adults

Aging is associated with progressive impairment of tissue and organ function, resulting in increased susceptibility to chronic disease, frailty and disability. Currently there are limited treatment options to alter this inevitable process. The proposed work has the potential to identify a new therapeutic intervention to decrease aging-related degenerative processes. Rapamycin or sirolimus is a macrocyclic immunosuppressive drug that inhibits the mammalian target of rapamycin (mTOR). The mammalian target of rapamycin (mTOR) pathway is part of phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR)-dependent pathway which is a fundamentally linked to cell metabolism, proliferation, differentiation, and survival. This pathway is altered in a variety of diseases, including cancers, immunosuppressed states, and fibroproliferative diseases. The mTOR kinase is considered one of the leading regulators of this pathway. Changes in mTOR signaling are closely associated with inflammation, cell growth and survival, leading to the development of chronic diseases. Recent evidence also suggests that mTOR inhibitors are promising modulators of the aging process by slowing the mechanisms of aging at the cellular level. There is a growing appreciation of the potential impact of sirolimus in slowing aging processes and in prolonging healthy lifespan. The proposed study addresses critical gaps in our understanding of the safety and efficacy of sirolimus in delaying aging processes and is based on findings in animal studies and incidental clinical observations. The investigators will overcome potential biases with a randomized control trial. The proposed intervention study is intended to improve our insight into clinical outcomes leading to prevention of chronic diseases such as skin cancer and mortality. Our overarching hypothesis is that sirolimus is one of the first pharmacological agents that will impact the aging process and chronic disease development. Specifically, the investigators aim to investigate whether sirolimus can reduce the occurrence or increase in biomarkers of aging processes.

Dystonia Genotype-Phenotype Correlation

The purpose of this study is to (1) investigate the effect of known dystonia-causing mutations on brain structure and function, to (2) identify structural brain changes that differ between clinical phenotypes of dystonia, and to (3) collect DNA, detailed family history, and clinical phenotypes from patients with idiopathic dystonia with the goal of identifying new dystonia-related genes. Investigators will be recruiting both healthy control subjects and subjects with any form of dystonia. For this study there will be a maximum of two study visit involving a clinical assessment, collection of medical and family history, task training session, an MRI using the learned tasks, and finally a blood draw for genetic analysis. In total, these visits will take 3-5 hours. If the dystonia subjects receive botulinum toxin injections for treatment, the participants and their matched controls will be asked to come for a second visit.

Resilience in Adolescent Development (RAD)

RAD is a 10-year natural history, longitudinal, prospective assessment study of a cohort of 2,500 participants (ages 10-24 years) that will help uncover the socio-demographic, lifestyle, clinical, psychological, and neurobiological factors that contribute to resilience among children, adolescents, and young adults at-risk for mood and anxiety disorders. As this is an exploratory study, we will assess a comprehensive panel of carefully selected participant specific parameters, including socio-demographic, life habits, clinical, biological, behavioral, neurophysiological, and neuroimaging. The study is designed to observe and collect factors associated with resilience in a non-invasive fashion; no interventions or treatments will be conducted during the project. Assessments will be conducted up to 4 times per year for up to 10 years, as well as a baseline visit. Study visits will be conducted in person whenever feasible but may be completed by phone/mail/computer, if an in-person visit is not possible.

Dallas 2K: A Natural History Study of Depression (D2K)

The primary objective of this initiative is to implement a prospective study that will allow us to identify and validate biosignatures of response to treatments for depression and depression outcome (using an integrated array of participant specific data: socio-demographic, lifestyle, clinical and behavioral assessments, fluid-based biomarkers, genomics, neuroimaging, EEG, and cell-based assays) in a longitudinal cohort of subjects with elevated symptoms of a depressive disorder. Symptom remission across various treatment options will be assessed using questionnaires for symptom changes, antidepressant treatment tolerability and overall quality of life. Other outcomes generated from this study will include rate of change in quantitative measures of brain function, of depression relevant brain regions correlated with systems-levels behavior and other functional neuro-circuitry MRI measures. Rate of change of specified biochemical biomarkers will also be assessed. Integration of these measures will provide an unmatched understanding into the mechanisms of depression and hold tremendous promise for better disease treatment and associated outcomes.

Pathway to Prevention Study

RATIONALE The accrual of data from the laboratory and from epidemiologic and prevention trials has improved the understanding of the etiology and pathogenesis of type 1 diabetes mellitus (T1DM). Genetic and immunologic factors play a key role in the development of T1DM, and characterization of the early metabolic abnormalities in T1DM is steadily increasing. However, information regarding the natural history of T1DM remains incomplete. The TrialNet Natural History Study of the Development of T1DM (Pathway to Prevention Study) has been designed to clarify this picture, and in so doing, will contribute to the development and implementation of studies aimed at prevention of and early treatment in T1DM. Purpose: TrialNet is an international network dedicated to the study, prevention, and early treatment of type 1 diabetes. TrialNet sites are located throughout the United States, Canada, Finland, United Kingdom, Italy, Germany, Sweden, Australia, and New Zealand. TrialNet is dedicated to testing new approaches to the prevention of and early intervention for type 1 diabetes. The goal of the TrialNet Natural History Study of the Development of Type 1 Diabetes is to enhance our understanding of the demographic, immunologic, and metabolic characteristics of individuals at risk for developing type 1 diabetes. The Natural History Study will screen relatives of people with type 1 diabetes to identify those at risk for developing the disease. Relatives of people with type 1 diabetes have about a 5% percent chance of being positive for the antibodies associated with diabetes. TrialNet will identify adults and children at risk for developing diabetes by testing for the presence of these antibodies in the blood. A positive antibody test is an early indication that damage to insulin-secreting cells may have begun. If this test is positive, additional testing will be offered to determine the likelihood that a person may develop diabetes. Individuals with antibodies will be offered the opportunity for further testing to determine their risk of developing diabetes over the next 5 years and to receive close monitoring for the development of diabetes.
